Abstract: PURPOSE: To obtain a field effect type liquid crystal display device having high transmissive characteristics of light which can be driven at a low voltage by dispersing plural transparent materials in a liquid crystal layer held between substrates which face each other and have electrodes on the inner surface so as to absorb or transmit incident light. CONSTITUTION: This liquid crystal electro-optical device consists of a pair of substrates 105 having electrodes 103 respectively on their inner surfaces opposite each other and a liquid crystal layer comprising liquid crystal molecules 101 held between the substrates 105. The liquid crystal layer contains a dichroic dye and has dispersion of plural transparent particles 102 in it so that incident light 106 is absorbed or transmitted by the dichroic dye. A voltage is applied from a power supply 104 to electrodes 103 to control the scattering of light caused between the liquid crystal material sealed between the substrates 105 and the transparent particles dispersed in the liquid crystal material and the scattering of light caused by minute orientation defects in the liquid crystal material to perform display.  The transparent particles dispersed in the layer are controlled to have the max. particle size smaller than the substrate gap, and thereby, a minute light scattering center is obtd.

Title: Surface hardening method for metallic pipe
Inventor: SHINOZUKA NORIO
IPC: B21D1/00
Filed: 1985-01-28
Abstract: PURPOSE:To harden uniformly the surface of a metallic pipe without causing the fluctuations of its length and diameter by passing a soft or semihard metallic pipe through a multiroll straightening machine equipped with straightening rolls having rubber-lined surfaces. CONSTITUTION:A soft or semihard metallic pipe is passed through a multiroll straightening machine equipped with straightening rolls 1 formed each by lining the surface of a roll 1 made of cast iron with a rubber or a similar elastic material 2 to provide a surface-hardening treatment to the pipe. As the hardness of soft or semihard metallic pipe is higher than that of the elastic body such as a rubber, a straightening force acting on the pipe is buffered by the rubber; accordingly the degree of hardening can be lowered, and the fluctuations of the diameter and length of pipe are decreased.

Title: Balancer for reciprocating engine
Inventor: TOKIYODA TETSUO
IPC: F16F15/26
Filed: 1987-01-26
Abstract: PURPOSE:To prevent the vibration of an engine by providing two balancer shafts rotating in mutually opposite directions below the engine, and fixedly providing inertial compensating balancers, and rotating a respective moment compensating balancer in a direction opposite to the rotational direction of a crankshaft. CONSTITUTION:Balancer shafts O1, O2 are provided on both downward sides of a crankshaft C, and rotated in mutually opposite directions at the number of revolutions according with the order of unbalanced force. Stationary inertial compensating balancers 5, 6 therefore generate force opposite to unbalanced inertia force occurring in the reciprocating direction of an engine for their mutual balance, and rotate in mutual opposite directions. Thus each force acting in mutually rectangular direction always balances with other ones. In addition to that, the primary and secondary moment compensating balancers 2, 3 rotate in a direction the same as or opposite to the rotational direction of the balancer shafts O1, O2 respectively to cause component parallel to the reciprocating direction of the engine to generate certain moment, which balances with the fluctuating unbalanced moment of the engine. An unbalanced inertia force can therefore balance with the moment to prevent the vibration of the engine.

Abstract: PURPOSE: To provide a digital weighing machine which has little electric loss and handles easily, by attaching a magnet to the rotary plate of the digital weighing machine and equipping a reed switch which detects the displacement of the magnet to supply electric power.  
     CONSTITUTION: A disc 7, which is rotated in proportion to weight, is provided with slits 8 located at an equal spacing on concentric circles. Light emitters 9, 10 and light receivers 11, 12 for changing a rotational angle into pulses are installed in positions corresponding to those of the slits. The output pulses from the light receivers 11, 12 are applied to a separately provided operation circuit to digitally indicate a measured value. The reason why the number of the pairs of the light emitters and receivers is two is to discriminate between forward and reverse rotation. The disc 7 is fitted with  magnet 15 and a reed switch 16. When the disc 7 is rotated over a prescribed displacement, the switch 16 is actuated to start supplying electric power. The the power is thus automatically supplied. This results in providing a weighing machine which has little electric loss and handles easily.
